I got about an average of 5-10 fps increase upgrading from 512 to 1GB of RAM. The biggest difference is you can preload your textures and skins, and still have memory left over for the computer to use. As FOGOLD said, its going to help smooth things out alot. With the new version I dont know what the change will be for you, if any. Results seem to be mixed. My frame rates increased with the update, as they did for many others. However, alot of other folks have noticed a drop in frame rates so who knows?
